Problems solved by technology

However, a disadvantage in known high-pressure exhaust gas recirculation systems is the reduced exhaust gas mass flow available to the exhaust gas turbocharger, which leads to reduced compressor efficiency and complex and thus expensive cooling of the recirculated exhaust gas, because these Factors usually come almost directly from the internal combustion engine

Embodiment Construction

[0028] according to figure 1 , the supercharged internal combustion engine 1 according to the invention has an exhaust gas turbocharger 2 comprising a turbine 3 and a compressor 4 . The exhaust gas turbocharger 2 is integrated here on the turbine side in the exhaust section 5 and on the compressor side in the intake section 6 of the internal combustion engine 1 , wherein a connecting exhaust section is additionally provided 5 and the exhaust gas recirculation line 7 of the intake section 6 . According to the invention, the exhaust gas recirculation line 7 branches off from the exhaust gas section 5 downstream of the turbine 3 of the exhaust gas turbocharger 2 and leads to the intake gas section 6 upstream of the compressor 4 . In addition, a valve device 8 for performing an open-loop / closed-loop control of the exhaust gas recirculation rate is arranged in the region of the exhaust gas recirculation line 7 .

[0029]By arranging the exhaust gas recirculation line 7 downstream...

Abstract

The present invention relates to a booster type internal combustion engine having an exhaust gas turbocharger (2), the exhaust gas turbocharger (2) is integrated into the exhaust section (5) on the turbine side and is integrated into the intake section (6) on the compressor side, and wherein there is provided an exhaust gas recirculation line (7) connected to the exhaust section (5) and the intake section (6). Importantly for the present invention herein, the exhaust gas recirculation line (7) in the turbine (3) downstream of the exhaust gas turbocharger (2) forks from the exhaust section (5), and upstream of the compressor (4) to the intake section (6), and the valve apparatus for performing the exhaust gas recirculation rate open loop / closed loop control valve apparatus (8) is arranged in the area of the exhaust gas recirculation pipeline (7).

Description

technical field [0001] The invention relates to a supercharged internal combustion engine with an exhaust gas turbocharger, which, according to the introduction of claim 1 , is integrated on the turbine side in the exhaust section and on the compressor side in the In the intake section of an internal combustion engine. Background technique [0002] From DE 10 2008 005 400 A1 a general internal combustion engine is known with an exhaust gas turbocharger, in which an exhaust gas recirculation line is provided connecting the exhaust section and the intake section. The exhaust gas recirculation line diverges from the exhaust gas section of the internal combustion engine upstream of the turbine of the exhaust gas turbocharger and leads again downstream of the compressor of the exhaust gas turbocharger to the intake section of the internal combustion engine, so that here In this case, it can be said that high-pressure exhaust gas recirculation. In this case, the exhaust gas reci...
